Is this 1,360-hp supercar cursed?
Almost exactly a year after a rare $1.5 million-plus Koenigsegg [
https://www.autoblog.com/category/koenigsegg/
] Agera RS crashed [
https://www.autoblog.com/2017/05/12/koenigsegg-agera-rs-crashes-in-testing/
] during testing in Sweden, it's happened again. To the same, repaired [
https://www.autoblog.com/auto-repair/
] supercar.
Swedish outlet Teknikens Varld reports [
http://teknikensvarld.se/koenigsegg-kraschade-i-trollhattan-i-dag/
] the crash happened last week after the Agera RS crashed into a ditch in a
rural area near the National Electric Vehicle Sweden (NEVS) headquarters
where Koenigsegg test-drives its cars. It confirms it's the same vehicle
that crashed in May 2017 after the driver lost control of it on the wet
track.
According to The Drive [
http://www.thedrive.com/news/20990/one-off-extremely-expensive-koenigsegg-agera-rs-crashes-during-testing-again
], it's an Agera RS Gryphon, an all-carbon fiber, 3,075-pound beast with
24-karat gold leaf trim that does a ridiculous 1,360 horsepower and 1,011
pound-feet of torque [
https://www.autoblog.com/2017/04/13/koenigsegg-agera-rs1-offers-1-360-hp-does-0-60-in-2-8-seconds/
]. It was originally built for U.S. car collector Manny Khoshbin before it
wrecked last year shortly before delivery.
The Swedish supercar maker reportedly set to work on a replacement Gryphon
following that wreck while pledging to repair the crashed model for use as a
factory test and demonstration car.
It's not clear what caused the most recent crash. The reader who submitted
the photo said it was clear from skid marks the car had been on both sides
of the road. It also wasn't clear whether the driver suffered any injuries.
Teknikens Varld says it's believed to be the first time the repaired car had
been driven in the open since the 2017 crash.
The Agera RS is the world's fastest production car [

Re: [EVDL] EV Brakes
Then again, the driver could be still hard braking. I have heard some people say that they frequently use the brakes to regen energy to extend range. Makes no sense whatsoever. Heavy regen is not free energy, it is exactly the opposite. Yes, it recovers maybe 55% of keinetic energy compared to an ICE car that throws away 100% of kinetic energy. But still you are wasting fully HALF of the battery energy used to get to speed. But if the car is not coming to a stop and the driver is only applying the brakes to slow down because she was otherwise going too fast for traffic and conditions, then that is no free energy, it is wasted energy. Sure it is less waste than an ICE, but it is still *very wasteful* compared to coasting to preserve ones kinetic energy instead. Just a possibility. This report claims 55% recovery during regen: http://proev.com/LLPgs/LLei0005.htm Again, any use of regen that is not for the purpose of coming to a required stop, is throwing away 50% of the car's kinetic energy, and is an indication that the car is tailgating or generally speeding above the average speed of vehicles in his lane (also wasting energy).

Re: [EVDL] Lots of 12v lithium batteries available.
Thanks Jerry, but I'd like to keep the lead-acid form factor and use the existing charger.
